No problem if you are getting out of rentals, but if you just plan to buy again in the near future, it makes no sense to sell.Paying off your mortgage to be debt free is an emotional decision, not a mathematical or financial decision in most cases.

In many cases, the heirs just don't want to deal with it, for emotional reasons or whatever.

Quote from @Matthew Paul: You were right to leave, but it sounds like you're allowing it to affect you emotionally.

This is not emotional, this is business.

I think emotionally they would rather do it now while she is alive vs after she passes. 

If the contract is incomplete or missing details, as stated several times above, whose position does that weaken?

There are two ways of addressing issues: fact-based and emotion-based.If the owner and 9-1-1 operator worked on facts, they wouldn't be concerned about firearms when conducting a welfare check on a tenant.

Solid offer, but they hired an engineer that basically convinced the home owners that the roof was going to collapse on itself, I HAD an engineer's report stating that everything was fine. 2nd offer busted....FINALLY, the 3rd offer closed....What a crazy journey, lots of emotions and frustration.

I just wanted to add, although your attorney may have already told you, that most states, I believe MA is one of them, have laws against "elderly abuse" where someone has taken financial, emotional or physical advantage of an elderly person. 

It was a lesson learned and let me emotions get the best of me when it came to chances.
